How do you determine which part of my track to use when previewing the master?

We give this control to you. We think you know best what part of the track will give you the results you’re looking for. Before sending the track for processing, you select a 30-second preview for us to use. If you want to hear how the mastering styles apply across different parts of the song, simply go back to step 1, and select a different part of the song, and try again.
